Name of the Mine
La Parilla Complex.

Location  
Durango state, Mexico.

Mine Owner/s  
Silver Storm Mining owns 100% of the La Parrilla Silver Complex.

Brief Description  
The La Parrilla property consists of 41 contiguous mining concessions covering a total of 69 478 ha.

The complex consists of five nonoperational underground mines, a nonoperational openpit mine and a 2 000 t/d processing facility.

Brief History  
La Parilla was in production continuously between 2005 and September 2019, when it was placed on care and maintenance. During this period, the complex collectively produced 34.3-million silver-equivalent ounces.

Silver Storm acquired the complex from First Majestic Silver in August 2023.

Primary Metals/Minerals  
Silver.

Secondary Metals/Minerals  
Gold, lead and zinc.

Geology/Mineralisation  
According to ‘Independent Technical Report for the La Parrilla Silver Project’, published in March 2025, La Parrilla is located at the transition between the Mesa Central and the Sierra Madre Occidental physiographic provinces of Mexico. 

La Parrilla district contains hydrothermal mineral deposits hosted by Early Cretaceous limestones and shales that have been intruded by an Eocene quartz monzonite-granodiorite stock, Oligocene dikes, rhyolite–rhyodacite dikes and plugs, and Miocene Quaternary basalt–basaltic andesite dikes. The Eocene-age stocks and dikes have metamorphosed the Cretaceous rocks into marble, hornfels, skarnoid and minor skarn. 

Mineralisation occurs as vein and replacement deposits, the locations of which are structurally controlled by pre-existing faults, fractures, and bedding planes. Veins can be either open space filling, forming massive sulphide and breccia veins, or fault-related, consisting of matrix-supported breccias or gouge containing disseminated sulphides and oxides. Gradations commonly occur between the two types in any vein system. Stockwork veining can occur at country rock/vein contacts. Replacement deposits occur as oblique or perpendicular splays to veins and faults, and as larger replacement deposits concordant with sedimentary bedding.

La Parrilla deposits contain primary sulphides such as galena, sphalerite, pyrite, pyrrhotite, arsenopyrite, chalcopyrite, covellite, acanthite, native silver, and silver sulphosalts (tetrahedrite freibergite solid solution). Owing to supergene oxidation, the primary sulphides in the upper parts of some deposits have been altered to cerussite, anglesite, hemimorphite, hydrozincite, jarosite, goethite, hematite, cervantite, malachite, chrysocolla, chalcanthite, and native silver.

Reserves  
Not stated.

Resources  
Total measured and indicated resources as at December 31, 2024, were estimated at 1.2-million grading 187 g/t silver, 0.1 g/t gold, 1.56% lead, 1.69% zinc and 280 g/t silver equivalent. Total inferred resources were estimated at 1.99-million grading 175 g/t silver, 0.12 g/t gold, 1.27% lead, 1.42% zinc and 255 g/t silver equivalent.

Type of Mine
Openpit and underground.

Mining Method  
Before being placed on care and maintenance in 2019, La Parrilla operated using overhand cut-and-fill stoping on near-vertical veins at its underground mines and conventional truck-and-shovel methods at its openpit operation.

Major Infrastructure/Equipment  
The supporting infrastructure for the operation is located near the plant and includes the main administrative offices, a sample preparation and assay laboratory, tailings facilities, maintenance buildings, cafeteria and other employee housing. The maintenance department operates from several repair shops and warehouses located at the plant site and adjacent to the mine.

Prospects  
Silver Storm partnered with subsidiaries of technology giant Samsung in October 2025 for offtake prepayment financing to restart the La Parrilla Silver Complex.

The funds will be used to restart operations, including mill rehabilitation and upgrading, underground development and working capital for the complex.

The offtake grants Samsung the right to purchase 100% of the lead/silver concentrate and the zinc concentrates produced at La Parrilla for a period of two years.
